Be it known that I, HENRI RUPERTI, a citizen of the German Republic, and'residing at Hamburg, Germany, have invented certain new and useful Improvements 1n Devices for Cleaning Pipes (for which I' have filed applications in Germany July 22, 1915, Patent No. 292,101, and in Switzerland June 3, 1916, Patent No. 73.671), of which the following is a specification.

This invention relates to van improved apparatus for cleaning pipes by means of a cleaning material under pressure, which 1s driven to and fro several times between two vessels. From the known devices having thev same object, the subject matter of the present invention is distinguished by the control of the pressure-medium being effected by means of a reversing-slide having corresponding ports and which is so mounted in the cover of the case-like device that for a passage of the pressure-medium therethrough the ports can be put in communication with U-shaped containers suspended from said cover and containing the cleaning-material and so arranged that the pres sure-medium, after passage through said containers, can again escape laterally from the device. In the annexed drawing, the device is represented in one suitable form of construction.

Fig. and

Fig. 2 is a plan view, ofthe device;y while Fig. 3 is a front-elevation of the same as attached to a beer pressure-apparatus The device comprises a case-like frame 1, two U-shaped glass-containers 2, 3, an upper part 4, a reversing-slide 5, and a closing lid 6.

The case-1ike frame 1 is so designed that vit offers a sufficient protection against damage to the glassecontainers 2, 3, while it serves at the same time as a stand and foot. The upper part 4 is fitted with tube-like studs 7, 8 which are connected with the orices 9, 10 ofthe glass-containers 2, 3 while they have outlets 11, 12.

In the upper part 4, the 'reversing-slide 5 is fitted, which is secured in position and guided by a closing-lid 6 on the upper part 4, The reversing-slide 5 is provided with- 1 is a longitudinal central section,`

handflever 13 and with ports 14, y15, ...which `are in communication with the orifices 16.

17 of the glass-containers 2, 3 by intermediarystrainers 18, 19. The U-shaped glasscontainers 2, 3 for the reception of the cleaning-material 2O are so connected with the upper part 4 of thedevice that their upper orifices 9, 10 and 16, 17 are in communication with the studs 7, 8 of the upper part 4 and with the ports 14, 15 of the slide.

The operation of the apparatus is as follows ry For cleaning, an appropriate wash is em ployed in connection with a solid scrubbing agent, in a way known in the art. The apparatus is so connected with the beer-piping to be cleaned that the ends of the latter, that are the upper cocks 21, 22 are in connection with the studs 7, 8 of the upperpart'4V by rubber pipes 25, 26 and the lower pipe ends are connected by a rubber pipe (see Fig. 3), so that the liquid can circulate therethrough. Thereupon, the reversing-slide 5 is connected with a water pressure-conduit 28 and so adjusted by means of the hand-lever 13 that .the pressure-water enters the glasscontainer 2, in which the cleaning-material 2O is filled. The latter mixed with the pressure-water is then driven through the stud 7 of the upper part 4 into the beer-piping, through which it runs while cleaning the same, whereupon it enters again they apparatus through thestud 8 and flows through the glass-contain`er 3 to an outlet 29. Previously, the solid cleaning-material 20 is, however, kept back by the strainer 19, while the residues from the beer-piping, which are .finely ground by said'cleaning-material, are

allowed to escape with the dirty water.

After reversion of the hand-lever 13 for about 450, the same process is repeated in op-posite direction. Said to-and-fro movement of the cleaning-material is, in a way known in the art, continued until the cleaning-water, which gets dirty by the residues in the beer-piping, remains perfectly clean, which can be easily 'observed through the transparent glass-containers.

What I claim, is

1. A device for cleaning pipes by means of a pressure-medium, particularly for beer pressure-apparatus, comprising, in combination, two U-shaped-glasscontaners inserted y in the piping to be cleaned for a passage of the pressure-medium therethrough, and a hand-operated reversing-slide to connect said containers for a control of the passage of the pressure-medium therethrouglnsubstantally as and for the purpose set forth.

2. A device for cleaning pipes `by means of a pressure-medium, particularly for beer pressureapparatns, Comprising, in combination, tivo U-shaped glass-containers inserted in the piping to be cleaned for a passage of the pressure-medium therethrough, a handoper'ated reversing-slide to connect said containers for a control of the passage of the pressure-medium therethrough, and a 15 strainer in the connection between each glass-container and said reversing-slide, substantlally as and for the purposev set forth.

In testimony whereof l have hereunto set 20 my hand in the presence of two subscribing Witnesses.
